Specifications from the supplier (Fiber Artist Supply Company):
The fringe twister is one of those weaving accessories that many weavers like to keep handy. To use, simply clasp a fringe in each clasp and wind your desired number of rotations. Keep track of the rotations as you continue to wind your fringes for perfect consistency. Our triple fringe twister is crafted from maple and steel hardware with rubber caps tightly fit onto the end.
